OutOfMemory Exception exporting PDF on x86 application

I'm testing Crystal Server 2013 SP01 trial.

I've create a test application to recreate a problem that we have on our customer.

The application is written in c# and use "SAP BusinessObject BI platform .NET SDK Redistributable 32bit 4.1 SP01", the Crystal Server is installed on a Windows Server 2008 R2. The client app and the crystal server are on the same machine.

The issue:

• If i build my application in x64 this work correctly and export a 174MB pdf file (182913169 byte)
• If i build my application in x86 throw an exception:

  • System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

       at CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArrayClass.get_ByteArray()

Can anyone help me?

Thanks
